Anatomy of Facial and Neck Muscles: Identification and Functions Quiz

Facial expressions are primarily controlled by the muscles in the face, not the muscles in the neck or chest.

The occipitofrontalis is a muscle that covers the top of the skull; the trapezius is a large muscle in the back and neck; the deltoid is a muscle in the shoulder; and the biceps brachii is a muscle in the upper arm.

The Platysma muscle is specifically located in the neck region and has the actions of covering all neck muscles, depressing the mandible, and tensing the skin of the neck. The other options provided are muscles responsible for different actions in the body.

The extrinsic eye muscles control the movement of the eyeball and coordination of eye movements. Each muscle has a specific direction in which it moves the eye, as represented in the correct answer options. Incorrect answers provided do not accurately describe the functions of the extrinsic eye muscles.

The genioglossus, hyoglossus, and styloglossus are all intrinsic muscles of the tongue responsible for its movements and functioning. The deltoid, biceps brachii, and rectus abdominis are not muscles directly related to the tongue.

The digastric muscle is responsible for opening the jaw by pulling the mandible down.

The sternocleidomastoid muscle is primarily responsible for movements involving the neck and head, not the eyes, toes, or knees.

The correct answer is 'bottom: depressor anguli oris' as it is the muscle responsible for lowering the corner of the mouth. The incorrect options are other muscles in the face with different functions.

The levator labii superioris muscle is responsible for elevating the upper lip, while the depressor labii inferioris muscle is responsible for depressing the lower lip. The incorrect answers do not match the specific muscles highlighted in the question.

The temporalis muscle is one of the primary muscles involved in closing the jaw during the process of chewing. The other incorrect options do not play a significant role in jaw closing movements.

The mylohyoid muscle is a flat muscle that forms the floor of the mouth and assists in swallowing.

The omohyoid muscle connects the shoulder to the hyoid bone, helping to stabilize the hyoid bone during swallowing and speech production. Sternocleidomastoid, trapezius, and deltoid are all muscles located in the neck and shoulder region, but do not directly connect the hyoid bone to the shoulder.

The Sternohyoid muscle is responsible for depressing the hyoid bone, while the other muscles listed are not directly involved in this specific movement.

The red highlighted area is specifically referring to the sternothyroid muscle, which is located in the neck region. The trapezius, thyrohyoid, and digastric muscles are all also located in the neck region but serve different functions.

The stylohyoid muscle is responsible for elevating and retracting the hyoid bone during swallowing. Pectoralis major is a chest muscle, soleus is a calf muscle, and temporalis is a muscle responsible for jaw movement.

The thyrohyoid muscle is located between the thyroid cartilage and the hyoid bone, responsible for raising the larynx.
